- Introduction: Diverse decision-making is needed in managing mass casualty incidents (MCIs), by emergency medical services (EMS). The aim of the study was to review consensus among international experts concerning policies of EMS management during MCIs. Methods: Applicability of 21 EMS policies was tested through a 2-cycle modified e-Delphi process, in which 38 multi-disciplinary experts from 10 countries participated. Threshold for approving proposed solutions was defined as consensus of amp;gt;80%. Policies that did not achieve the targeted consensus were reviewed to detect variability according to respondents origin country. Results: 16 policies were endorsed in the first cycle including collaboration between ambulance service providers; implementing a unified mode of operation; preparing criteria for ground versus aerial evacuation; and, developing support systems for caregivers exposed to violence. An additional policy which proposed that senior EMS officers should not necessarily act as on-site MCI commanders was endorsed in the second cycle. Demographic breakdown of views concerning non-consensual policies revealed differences according to countries of origin. Assigning ambulances to off-duty team members was highly endorsed by experts from Israel and South Africa and strongly rejected by European respondents. Avoiding entry to risk areas until declared safe was endorsed by European, Asian and Oceanic experts, but rejected by Israeli, South African and North American experts. Conclusions: Despite uniqueness of countries and EMS agencies, solutions to most dilemmas were applicable to all organizations, regardless of location or affiliation. Cultural diversity was found concerning readiness to implement military-civilian collaboration in MCIs and a rigid separation between work-leisure responsibilities. (C) 2017 Elsevier Ltd.

- Introduction: Depressive symptoms occur in approximately half of trauma patients, negatively impacting on functional outcome and quality of life following severe head injury. Pontine noradrenaline has been shown to increase upon trauma and associated beta-adrenergic receptor activation appears to consolidate memory formation of traumatic events. Blocking adrenergic activity reduces physiological stress responses during recall of traumatic memories and impairs memory, implying a potential therapeutic role of beta-blockers. This study examines the effect of pre-admission beta-blockade on post-traumatic depression.Methods: All adult trauma patients (>= 18 years) with severe, isolated traumatic brain injury (intracranial Abbreviated Injury Scale score (AIS) >= 3 and extracranial AIS <3) were recruited from the trauma registry of an urban university hospital between 2007 and 2011. Exclusion criteria were in-hospital deaths and prescription of antidepressants up to one year prior to admission. Pre- and post-admission beta-blocker and antidepressant therapy data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. Patients with and without pre-admission beta-blockers were matched 1: 1 by age, gender, Glasgow Coma Scale, Injury Severity Score and head AIS. Analysis was carried out using McNemar's and Student's t-test for categorical and continuous data, respectively.Results: A total of 545 patients met the study criteria. Of these, 15% (n = 80) were prescribed beta-blockers. After propensity matching, 80 matched pairs were analyzed. 33% (n = 26) of non beta-blocked patients developed post-traumatic depression, compared to only 18% (n = 14) in the beta-blocked group (p = 0.04). There were no significant differences in ICU (mean days: 5.8 (SD 10.5) vs. 5.6 (SD 7.2), p = 0.85) or hospital length of stay (mean days: 21 (SD 21) vs. 21 (SD 20), p = 0.94) between cohorts.Conclusion: beta-blockade appears to act prophylactically and significantly reduces the risk of posttraumatic depression in patients suffering from isolated severe traumatic brain injuries. Further prospective randomized studies are warranted to validate this finding.

- INTRODUCTION: A significant proportion of patients suffer depression following traumatic injuries. Once manifested, major depression is challenging to overcome and its presence risks impairing the potential for physical rehabilitation and functional recovery. Risk stratification for early detection and intervention in these instances is important. This study aims to investigate patient and injury characteristics associated with an increased risk for depression.METHODS: All patients with traumatic injuries were recruited from the trauma registry of an urban university hospital between 2007 and 2012. Patient and injury characteristics as well as outcomes were collected for analysis. Patients under the age of eighteen, prescribed antidepressants within one year of admission, in-hospital deaths and deaths within 30days of trauma were excluded. Pre- and post-admission antidepressant data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. To isolate independent risk factors for depression a multivariable forward stepwise logistic regression model was deployed.RESULTS: A total of 5981 patients met the inclusion criteria of whom 9.2% (n=551) developed post-traumatic depression. The mean age of the cohort was 42 [standard deviation (SD) 18] years and 27.1% (n=1620) were females. The mean injury severity score was 9 (SD 9) with 18.4% (n=1100) of the patients assigned a score of at least 16. Six variables were identified as independent predictors for post-traumatic depression. Factors relating to the patient were female gender and age. Injury-specific variables were penetrating trauma and GCS score of≤8 on admission. Furthermore, intensive care admission and increasing hospital length of stay were predictors of depression.CONCLUSION: Several risk factors associated with the development of post-traumatic depression were identified. A better targeted in-hospital screening and patient-centered follow up can be offered taking these risk factors into consideration.

Journal article (peer-reviewed)abstract
- ObjectivesTo validate the classification of surgically treated acetabular fractures in the Swedish Fracture Register (SFR) and to investigate the intra- and interrater reliability of the Judet-Letournel / AO/OTA classification systems.MethodsSurgically treated acetabular fractures were randomly selected from the SFR (n = 132) and 124 fractures were classified independently by three experienced orthopedic pelvic surgeons at two different occasions. A gold standard classification was established for each case after these two sessions or, if necessary, after a discussion session. The gold standard classification was compared to the registered SFR classification to assess the validity of SFR data. Accuracy and intra- and interrater agreement were evaluated using Cohen's kappa with interpretation according to Landis and Koch.ResultsThere was moderate agreement between the established gold standard classification and the SFR (kappa 0.43). The level of agreement differed between classification groups. The intrarater agreement was substantial to almost perfect and interrater agreement was moderate to substantial.ConclusionsThe accuracy of acetabular fracture classifications in the SFR was moderate and comparable to previous validation studies from the SFR on other fracture types. As the accuracy differed between fracture groups, care should be taken when analyzing data from the SFR on specific acetabular fracture groups.

- INTRODUCTION: The recommended urgent surgical management of ocular motility restriction due to orbital muscle entrapment or impingement associated with orbital wall fracture needs to be elucidated.AIM: To evaluate the importance of the time from injury to surgery for the outcome in ocular motility and diplopia, the time lapse of ocular motility, diplopia and hypesthesia recovery.MATERIAL AND METHODS: Patients with entrapment or impingement of orbital contents due to orbital wall fracture were followed up prospectively over 1year regarding ocular motility, diplopia, hypesthesia and cosmetic deformity.RESULTS: 21 patients (10 entrapments and 11 impingements) were included and treated surgically. The median time from injury to surgery was 36 (8-413)h for the entrapment group and 168 (48-326)h for the impingement group. The median time from study inclusion to surgery was 0 (0-1) days for the entrapment group and 1.0 (0.2-4.8) days for the impingement group. All the patients had ocular motility limitation and diplopia at the inclusion. Ocular motility improved gradually and was normal at final visit. Diplopia resolved gradually in all patients except in two with non-disturbing diplopia, at the final visit. Forced duction test was positive in 90% of the patients in the entrapment group and 70% in impingement group. At final visit, hypesthesia was found in none of the patients in the entrapment group but in 4 patients in the impingement group.CONCLUSIONS: In this, the first prospective long term follow up of orbital wall fractures with ocular motility restriction, we did not find any significant correlation between the time from injury to surgery and the outcomes in ocular motility and diplopia. An entrapment requires surgery as soon as possible; however, the surgical reduction is at least as important as surgical timing. Surgery should be delayed until it can be performed by an experienced surgeon. Ocular motility restriction causing diplopia due to impingement is not an ophthalmologic emergency and surgery is recommended if the diplopia and ocular motility has not improved over time. Clinical examination of ocular motility and not CT scan findings is crucial to determine whether a limitation of ocular motility exists or not.

- When stress fractures started to show up in the femurs of elderly ladies, it was soon evident that bisphosphonate use lay behind, and the absolute risk increase due to bisphosphonate use was reasonably well estimated already in 2008. Thereafter followed a period of confusion: the term atypical fracture was introduced, with a definition so vague that the true stress fractures tended to disappear in a cloud of ambiguity. This cast doubt on the association with bisphosphonates. The association was then re-established by large epidemiological studies based on radiographic adjudication. Atypical fractures are largely caused by bisphosphonates. With a correct indication, bisphosphonates prevent many more fractures than they cause, at least during the first years of use. With an incorrect indication they are likely to cause more harm than good. (C) 2016 Elsevier Ltd. All rights reserved.

The revised cardiac risk index is associated with morbidity and mortality independent of injury severity in elderly patients with rib fractures
- 2023
-
In: Injury. - : Elsevier. - 0020-1383 .- 1879-0267. ; 54:1, s. 56-62

Journal article (peer-reviewed)abstract
- BACKGROUND: Risk factors for mortality and in-hospital morbidity among geriatric patients with traumatic rib fractures remain unclear. Such patients are often frail and demonstrate a high comorbidity burden. Moreover, outcomes anticipated by current rubrics may reflect the influence of multisystem injury or surgery, and thus not apply to isolated injuries in geriatric patients. We hypothesized that the Revised Cardiac Risk Index (RCRI) may assist in risk-stratifying geriatric patients following rib fracture.METHODS: All geriatric patients (age ≥65 years) with a conservatively managed rib fracture owing to an isolated thoracic injury (thorax AIS ≥1), in the 2013-2019 TQIP database were assessed including demographics and outcomes. The association between the RCRI and in-hospital morbidity as well as mortality was analyzed using Poisson regression models while adjusting for potential confounders.RESULTS: 96,750 geriatric patients sustained rib fractures. Compared to those with RCRI 0, patients with an RCRI score of 1 had a 16% increased risk of in-hospital mortality [adjusted incidence rate ratio (adj-IRR), 95% confidence interval (CI): 1.16 (1.02-1.32), p=0.020]. An RCRI score of 2 [adj-IRR (95% CI): 1.72 (1.44-2.06), p<0.001] or ≥3 [adj-IRR (95% CI): 3.07 (2.31-4.09), p<0.001] was associated with an even greater mortality risk. Those with an increased RCRI also exhibited a higher incidence of myocardial infarction, cardiac arrest, stroke, and acute respiratory distress syndrome.CONCLUSIONS: Geriatric patients with rib fractures and an RCRI ≥1 represent a vulnerable and high-risk group. This index may inform the decision to admit for inpatient care and can also guide patient and family counseling as well as computer-based decision-support.

- INTRODUCTION: Hip fractures constitute a major and growing public health problem amongst the elderly worldwide. We examined the association of anthropometry and physical activity with hip fracture incidence in a cohort of elderly Europeans, participants in the European Prospective Investigation into Cancer and nutrition (EPIC) study. MATERIALS AND METHODS: The study population consisted of 27982 volunteers (10553 men and 17429 women) aged 60 years and above from five European countries. Information on anthropometry, physical activity, medical history and other characteristics was collected at baseline. During a median follow-up of 8 years, 261 incident hip fractures (203 women and 58 men) were recorded. Data were analysed through Cox proportional hazard regression with adjustment for potential confounders. RESULTS: A higher body mass index (BMI) was associated with lower hip fracture risk (hazard ratio (HR) per increasing sex-specific-quintile: 0.85, 95% confidence interval (95% CI): 0.77-0.94). Body height was associated with increased hip fracture risk (HR per 5cm: 1.13, 95% CI: 1.01-1.25). Waist-to-hip ratio was not related to hip fracture risk. Increasing levels of leisure-time physical activity were related to lower risk (HR per increasing tertile: 0.84, 95% CI: 0.70-0.99, p for trend: 0.039). CONCLUSIONS: In a prospective cohort study of elderly Europeans, we found evidence that high body stature increased and high BMI decreased the incidence of hip fractures. After adjustment for BMI, waist-to-hip ratio was not associated with hip fracture risk. Leisure-time physical activity appears to play a beneficial role in the prevention of hip fractures.

Anti-RANKL treatment improves screw fixation in cancellous bone in rats

Journal article (peer-reviewed)abstract
- Bisphosphonates improve implant fixation in randomised clinical trials of knee prostheses, hip prostheses and dental implants. However, a limited amount of bone resorption is required for bisphosphonates to exert an effect. Anti-RANKL treatment does not have this limitation, and we therefore tested whether if they might be more effective for improvement of implant fixation. This is of interest, as anti-RANKL treatment with denosumab is now in common clinical use. Male SD rats received a stain-less steel screw in the right proximal tibia and a drill hole in the left (n = 42). They were randomised to subcutaneous injections of either alendronate (20 mu g/kg/day), alendronate (200 mu g/kg/day), osteoprotegerin with an Fc tag (OPG-Fc; 8 mg/kg, twice weekly), or saline control. After 4 weeks, the fixation of the steel screw was measured by pull-out test. The tibia with the drill hole was evaluated with mu CT. OPG-Fc increased the pull-out force compared to saline controls by 153% (p less than 0.001). There was no significant difference between OPG-Fc and the alendronate groups. OPG-Fc increased the bone density (BV/TV) in the previous drill hole compared to controls 7-fold (p less than 0.001). This increase was higher than with any alendronate dose (p less than 0.001). OPG-Fc increased the bone density of the L5 vertebral body, but there was no significant difference between OPG-Fc and alendronate. Our results suggest that screw fixation in cancellous bone can be dramatically improved by an antiRANKL agent. The effect was comparable to very high bisphosphonate doses. Screw insertion in cancellous bone elicits a metaphyseal fracture healing response, and our findings might be relevant not only for implant fixation, but also for fracture healing in cancellous bone.

Journal article (peer-reviewed)abstract
- BACKGROUND: Access to pre-hospital trauma care can help minimize many of traffic related mortality and morbidity in low- and middle-income countries with high rate of traffic deaths such as Iran. The aim of this study was to assess if the distribution of pre-hospital trauma care facilities reflect the burden of road traffic injury and mortality in different provinces in Iran. METHODS: This national cross-sectional study is based on ecological data on road traffic mortality (RTM), road traffic injuries (RTIs) and pre-hospital trauma facilities for all 30 provinces in Iran in 2006. Lorenz curves and Gini coefficients were used to describe the distributions of RTM/RTIs and pre-hospital trauma care facilities across provinces. Spearman rank-order correlation was performed to assess the relationship between RTM/RTI and pre-hospital trauma care facilities. RESULTS: RTM and RTIs as well as pre-hospital trauma care facilities were distributed unequally between different provinces. There was no significant association between the rate of RTM and RTIs and the number of pre-hospital trauma care facilities across the country. CONCLUSIONS: The distribution of pre-hospital trauma care facilities does not reflect the needs in terms of RTM and RTIs for different provinces. These results suggest that traffic related mortality and morbidity could be reduced if the needs in terms of RTM and RTIs were taken into consideration when distributing pre-hospital trauma care facilities between the provinces.

- Introduction: The fixation of small intraarticular bone fragments is clinically challenging and an obvious first orthopaedic indication for an effective bone adhesive. In the present study the feasibility of bonding freshly harvested human trabecular bone with OsStic(R), a novel phosphoserine modified cement, was evaluated using a bone cylinder model pull-out test and compared with a commercial fibrin tissue adhesive. Methods: Femoral heads (n=13) were collected from hip fracture patients undergoing arthroplasty and stored refrigerated overnight in saline medium prior to testing. Cylindrical bone cores with a pre-inserted bone screw, were prepared using a coring tool. Each core was removed and glued back in place with either the bone adhesive (alpha-tricalcium phosphate, phosphoserine and 20% trisodium citrate solution) or the fibrin glue. All glued bones were stored in bone medium at 37 degrees C. Tensile loading, using a universal testing machine (5 kN load cell), was applied to each core/head. For the bone adhesive, bone cores were tested at 2 (n=13) and 24 (n=11) hours. For the fibrin tissue adhesive control group (n=9), bone cores were tested exclusively at 2 hours. The femoral bone quality was evaluated with micro-CT. Results: The ultimate pull-out load for the bone adhesive at 2 hours ranged from 36 to 171 N (mean 94 N, SD 42 N). At 24 hours the pull-out strength was similar, 47 to 198 N (mean 123 N, SD 43 N). The adhesive failure usually occurred through the adhesive layer, however in two samples, at 167 N and 198 N the screw pulled out of the bone core. The fibrin tissue adhesive group reached a peak force of 8 N maximally at 2 hours (range 2.8-8 N, mean 5.4 N, SD 1.6 N). The mean BV/TV for femoral heads was 0.15 and indicates poor bone quality. Conclusion: The bone adhesive successfully glued wet and fatty tissue of osteoporotic human bone cores. The mean ultimate pull-out force of 123 N at 24 hours corresponds to similar to 300 kPa shear stress acting on the bone core. These first ex-vivo results in human bone are a promising step toward potential clinical application in osteochondral fragment fixation. (C) 2022 The Authors. Published by Elsevier Ltd.

Journal article (peer-reviewed)abstract
- BACKGROUND: Pelvic ring fractures caused by high-energy trauma are severe injuries with well described radiological and clinical outcomes, whereas description from the patient's perspective is less well documented. The purpose of this study was to investigate patient-reported outcome following surgical treatment of pelvic fractures using quality of life instruments.METHODS: All 54 patients (28 male/26 female, ages 16-68) with pelvic fractures referred to our institution for surgical treatment 2003-2005 were prospectively included. The most common trauma was motor vehicle accident (44%). Additional injuries were seen in 74% and in 31% the ISS was >or=16. There were 31 B and 23 C type fractures. Patients were followed for two years using two validated questionnaires, SF-36 and LiSat-11, the latter an instrument consisting of 11 questions for evaluation of satisfaction with different aspects of life.RESULTS: 45 patients could be followed according to the study protocol for two years while 2 were untraceable and 1 died from unrelated causes. Of 6 nonresponders, 5 were unable due to psychiatric disorder. At two years pelvic fracture patients scored lower than the reference population in both physical and mental domains (SF-36). Highest mean score, 68, was in the domain Social Function (norm 89) while lowest mean score, 38, was in the domain Role Physical (norm 86). The mean score closest to the normative was for general health with 61 for patients and 78 for the normative group. In LiSat-11 pelvic fracture patients scored lower than the reference population in all areas. Satisfaction with life as a whole was 31% compared with 60% in the normative group.CONCLUSIONS: Two years after surgical treatment of pelvic ring fractures, patients reported substantially lower quality of life for both physical and mental domains, when compared with a reference population, even when radiological and clinical outcomes were considered favourable.

- The challenge of caring for patients with fragility fractures is particularly acute for nursing teams who are in short supply and work with patients following fracture on a 24 h basis, coordinating as well as providing complex care. This paper considers the role of nurses within the orthogeriatric team and highlights the value of effective nursing care in patient outcomes. It explores the nature of nursing for patients with fragility fracture with a focus on the provision of safe and effective care and the coordination of care across the interdisciplinary team. It also highlights the need for specific skills in orthopaedic and geriatric nursing as well as specialist education. (C) 2018 Elsevier Ltd. All rights reserved.

Journal article (peer-reviewed)abstract
- BACKGROUND: The adrenal response in critically ill patients, including trauma victims, has been debated over the last decade. The aim of this study was to assess the early adrenal response after trauma. METHODS: Prospective, observational study of 50 trauma patients admitted to a level-1-trauma centre. Serum and saliva cortisol were followed from the accident site up to five days after trauma. Corticosteroid binding globulin (CBG), dehydroepiandrosterone (DHEA) and sulphated dehydroepiandrosterone (DHEAS) were obtained twice during the first five days after trauma. The effect of time and associations between cortisol levels and; severity of trauma, infusion of sedative/analgesic drugs, cardiovascular dysfunction and other adrenocorticotropic hormone (ACTH) dependent hormones (DHEA/DHEAS) were studied. RESULTS: There was a significant decrease over time in serum cortisol both during the initial 24 h, and from the 2nd to the 5th morning after trauma. A significant decrease over time was also observed in calculated free cortisol, DHEA, and DHEAS. No significant association was found between an injury severity score >/= 16 (severe injury) and a low (< 200 nmol/L) serum cortisol at any time during the study period. The odds for a serum cortisol < 200 nmol/L was eight times higher in patients with continuous infusion of sedative/analgesic drugs compared to patients with no continuous infusion of sedative/analgesic drugs. CONCLUSION: Total serum cortisol, calculated free cortisol, DHEA and DHEAS decreased significantly over time after trauma. Continuous infusion of sedative/analgesic drugs was independently associated with serum cortisol < 200 nmol/L.
